Frequently Asked Questions

Everything you need to know about MyGug

Biogas is not dangerous. All types of gas by nature are flammable and will ignite if there is a large concentration present in the air. However Biogas is safer than LPG, Butane or Propane in that the gas is not compressed in large amounts in cylinders but stored in a soft and robust PVC biogas bag. Because the biogas is not compressed but is stored at atmospheric pressure (i.e. the same pressure as the air around you) there is a far less chance of a leak from the bag. The quantity of gas being stored in a MyGug biogas bag is small also and is being produced all the time so there is not a big reservoir of gas which can be dangerous. Gas cylinders on the other hand are at high pressure and the quantities of gas are very large so hold a lot more potential energy and risk.  All our digesters are certified for safety and have the CE mark.

MyGug uses a natural process called Anaerobic Digestion to convert your food waste to free sources of energy (biogas) for cooking and nutrient-rich liquid bio-fertiliser to use in your garden and poly tunnel. See our video on the home page for more information.

The MyGug models vary in size with our smallest domestic model “MyGug Micro” taking 1.5kg on average per day and other commercial models taking more depending on the size. The MyGug models have something to suit everyone. See the shop page for more information on our MyGug system sizes. 

Yes! MyGug will happily digest all of your cooked and raw food waste. The real benefit of Micro Anaerobic Digestion is that it will accept all organic food waste: cooked foods of all types and leftovers, vegetable peelings, grease and oily waste, mayonnaise and all sauces , chicken, fish and all meats, ice cream, beer, wine and milk. MyGug will turn all of these solid and liquid food wastes into biogas and organic bio-feriliser. If you are using your digestate for growing vegetables we do not recommend you dispose of raw meats but cook them before putting in the digester.

MyGug is very easy to use. It sits in your garden and comes with a small sink and macerator unit. Put your food waste into the sink, turn on the tap and press the button. It is as simple as that.

No, All parts of MyGug are fully enclosed so there is no way for smells to escape. We recommend that the sink is cleaned down with half a lemon occasionally. 

A domestic scale MyGug will give you between 1-2 hours cooking time per day (usually about 200L to 400L of biogas per day). For commercial digesters a good rule of thumb is every 10kg of food waste will produce the equivalent of 1kg of compressed gas. Some food waste will produce more biogas than other types of food waste. For example Diary, bread, grease and oily food waste will produce more biogas than vegetable waste.
MyGug is a fully automated system and shows the user when it has reached it’s capacity so that you don’t overfill!

No. It is not ok to dispose of non food waste. Any plastics, paper or other non food items can damage the system and interfere with it’s proper functioning.

By using MyGug, the need to store food waste in the home is no longer an issue, bin collections are no longer required, landfills are not needed and carbon emissions are reduced as you have a safe and economical method of disposing of food waste in your home or business. Because MyGug creates biogas from your food waste you will also be reducing your usage of fossil fuel derived gas and you will have an abundance of rich bio fertiliser for growing food and feeding plants. 

The egg shape is really good for mixing the contents of the egg (no corners or dead zones for solids to settle in), the egg shape is inherently a very strong shape (from nature!) and allows for excellent functioning. It is also designed to nestle in nicely to any landscape. 

Yes. Gp to the Shop Page and contact us at hello@mygug.eu with nay further questions 

We don’t put grass directly into the digester. You can however capture much of the energy from your grass clippings if you put them in any type of tank or even a plastic sheet that will capture the runoff as the grass breaks down. This is a strong brown liquid and this liquid can be poured directly into the sink where it will then be pumped to the digester giving you back energy in the form of biogas. MyGug is not designed to accept human waste.

We do not really compress the gas, we only slightly pressurise it. We pressurise the gas to about 23millibar (mbar). This is only 23cm of water head which is all that is required for a standard cooker. Gas is normally compressed to enable it to be transported. Natural gas is compressed up to 250 Bar (250,000mbar) which is over 10,000 times the pressure that is required at the cooker (a regulator reduces this pressure to 23mbar). As our units produce biogas all the time there is no transport requirement so we do not waste energy compressing it into a cylinder.

We supply a biogas hob with the system so you can use the gas for cooking safely and efficiently. 

MyGug has automated controls and is designed to work as efficiently in winter as in summer and in all climates. 

A domestic unit requires about 2m x 1.5m space. Larger and smaller biogas storage bags are available. The MyGug can be placed near the house.
